All right, fine. Let's use your definitions. Here is a report from the US in 2022:
https://pmc.ncbi.nlm.nih.gov/articles/PMC9555285/From 2013-2020 in Northern California we have:
> Among the 209 adolescents who underwent gender-affirming mastectomy, only two expressed regret.
> In our cohort, two patients (0.95%) expressed regret; one inquired about reversal surgery, but neither had undergone reversal surgery within follow-up periods of 3.7 years and 6.5 years.
Note the followups are into post-teenage years and most are very satisfied.
> Gender-affirming mastectomy, also known as “top surgery,” is the most prevalent surgery requested when considering all transgender adolescents, whereas “bottom surgery,” which affects genitalia and fertility, is relatively more complex and mostly performed after age 18.
As far as I can see, this is a medical system that is being very conservative (especially involving irreversible effects on fertility), involving parents/guardians at all stages, and prefers therapy first, hormones second, and surgery only as a very final choice. And note this level of conservatism in a system in Northern California--which is likely to be the most accepting of such medical actions.
So, if you are advocating that this should not be the case, understand that you are directly attempting to legislate the complex relationship between parent and teenager as well as both of them communicating with a medical professional for something which evidentially is a neutral to positive outcome for 98+% of the patients involved.
What right do YOU think you have to enter into that conversation at all?
